I have about 10 windows of Chrome open with a total of about 80 tabs. I'm going to buy a new computer, and I want to open all the windows with the same tabs on the new computer. Is it possible to do it and how? I can sync Chrome to my Google account and then sync it again from the new computer, but how do I open again all windows and tabs?
Make sure sync is enabled on both devices.
On your new device, open chrome and open the history (CTRL+H on windows). On the left-side there is an option for Tabs from other devices and clicking on it should shows your old device and a list of all the tabs open on it.
In the history view find your old device and click the three-dots button that is on the right-side of the header bar. There will be an option there to Open all.
